That's because their isn't enough mercury in it, so the phosphors glow dimly. This is called mercury starvation.

Mercury starvation This thing is not found in high school .tube light bulbs chapter. I luckely see this phenomenon at the age of 15 in 15 watt cfl

I always keep the electronics out of one of those CFLs because they always have at least one and often two ferrite cores which are great for winding a Joule Thief coil. There's always a toroid core in there, and often you'll find another, cylindrically wound coil. You can unwind the cylindrically wound coil and you get enough wire to both re-wind the coil for a Joule Thief and to wind a new Joule Thief coil on the toroid. If there's only the toroid, you can steal the wire for the Joule Thief coil from the inductor. I haven't tried to re-wind the inductor yet, because it's too difficult to get it unwound while preserving the ferrite core intact. Still, getting two coils out of one CFL is pretty good. I've wired the Joule Thief circuit into a few of those cheap LED chains which normally use two AA cells in series so that you can use just one cell to drive the LEDs. My impression has been that it runs at least as long with only one cell going through the Joule Thief circuit as it did with two cells directly driving the LED chain.

Last time I was making a joule thief out of such CFL I was amazed how many components are in it.

I wonder if something has changed that reduced the effective florescence of the phosphor. I remember that there was a reasonably common failure mode with CCFL LCD panels in laptops where the backlight would turn pink, it was always the CCFL in the panel that had become faulty.

This one is new, it is like this from the beginning. The phosphor seems ok, but the gas filling is probably wrong. Normally, you can see the typical cyan glow of mercury at the ends of the tube where the phosphor is missing. Threre's no cyan glow.

I've been wanting one of these bad bulbs for some time now since they just look really cool in my opinion and I have made a driver for it already, working well on working tubes but I don't have any of these worn out tubes yet. Edit 1 year later: I finally got one, though unfortunately my driver cannot drive it since it's 22 watts or maybe 27, and my driver can only do about 15 so the tube does not fully start.

here did the mercury go? im asking because i have a cfl it has the same fault but it was working fine for about 6 mounts

Old lamps may lose mercury by absorption.

The tube is mercury starved

Can you explain how your power strip is a power meter?

This phenomen is common in Osram LUMILUX bulbs.I my primary school i saw this phenomen few times.Ballast was electronic and electromagnetic with bi metal starter.

Мощность лампы при поднесении к ней магнита увеличивается из-за того, что индуктивность досселя, который ограничивает ток лампы, падает. Так делать не очень хорошо; если переборщить, можно испортить электронный балласт.

i have the same Problem with a 58w ge flurescent tube theres no Mercury inside

how did you make your wattmeter?

@DiodeGoneWild, how can we suggest a teardown?

It would be interesting to see the spectrum through a diffraction grating.

Mercury starved fluorescent tube. Normally CFLs doesn't get mercury starved, this is the first time I see it. Or it could have been that the driver failed and the tube received enough voltage for arc ignition but not much current at all so the discharge is so weak it does not produce enough UV to excite any other phosphor that is in the triphosphor blend and only excites the one that is easiest, witch is the pink one thus the tube glows pink. I have seen it happen in cheap electronic ballasts. Philips TL-D Master F36T8 Warm white tubes lit up in barely visible pink color because driver does not provide enough arcing current and the tube is extremely dim.Usually if that happens it means that the switching transistor is bad and doesn't switch at a high current

I hope you have a good RCCB.

What an odd effect, did you try a pcb from another flourescent bulb, perhaps slightly more modern with two transistors? I keep the pcbs from the ones with dead tubes, most pcbs checkout fine, i dont like throwing away usable parts.

The tube actually runs on high frequency AC square wave. Polarity doesn't matter. The only important thing, is that each filament is connected to it end of the power supply. It's basically a "rapid start" configuration, but runs at about 40 kHz.

I think the power goes up with the magnetic field because of earlier saturation of the inductors

The mercury leaked out and it left the argon behind so it is just an argon discharge

@gabracal

4 жыл бұрын

But if the mercury leaked out, how come the argon is still in the tube? Shouldn't the argon be displaced with air since the tube is under a vacuum?

This color is so cool and it probably takes more power because the magnets atracts the electrons in the tube and makes it easear for them to get from the cathode to the anode

The mercury could have also leaked out before it was sealed with argon.

I still use some of them ;-)

Are we sure bi clive didn't get to it first?

Argon or neon gas

It's pink due to mercury adsorption

Look up magnetic hysteresis. The magnet saturates the transformer core reducing the efficiency. You can burn out the power supply by subjecting it to the magnet. More study on the subject en.wikipedia.org/wiki/Saturable_reactor

The inductor acts as a ballast, it limits the current and thefore the power to the tube, when you put it near to the magnet the inductor core starts to saturate, this will allow more cirrent through the inductor increasing the power.

@mortlet5180

6 жыл бұрын

Splitfire pilot; No, the magnet causes emitted electrons to spiral through the gas path, ionising more of the gas in the process. More ions causes more currenr flow at mostly the same voltage. Secondly, he didn't have the ferrite close enough to the magnet for what you suggested to happen. The transformer would also saturate in that case anyway, causing the power to drop. Which one will win in that case, I don't know, but it will definitely not just be like the choke isn't there.

@seandoofer5720

6 жыл бұрын

Accepted your probably right about the chemistry, not my scene. And yes a transformer secondary output would reduce if saturated, however the few Cfl's I've pulled to bits used a choke not a transformer.
